A 13-year-old, spayed, female Chihuahua dog was referred for evaluation of fever, lethargy, and dyspnea. Hematologic evaluation revealed severe neutropenia, thrombocytopenia, and mild anemia. The dog had been undergoing phenobarbital therapy for the past 7 weeks because of generalized seizures due to meningoencephalomyelitis of unknown etiology. After ruling out other possible causes of cytopenias, a tentative diagnosis was made of drug-induced blood cell dyscrasia. The neutropenia and thrombocytopenia resolved after discontinuation of phenobarbital (8 days and 15 days after discontinuation, respectively). This is the first case report in Korea to demonstrate blood dyscrasia associated with idiosyncratic adverse effects of phenobarbital.

Paratuberculosis caused by Mycobacterium avium subsp. paratuberculosis (MAP) has extended latent periods of infection. Due to this property, difficulties in the detection of fecal shedder have been raised. A newly designed method for DNA extraction from fecal specimens, mGITC/SC was evaluated in terms of diagnostic efficiency. The detection limit of IS900 real-time PCR was about 50 MAP (1.5 cfu) in 250 mg of feces (6 cfu per g). Also, this DNA extraction method was faster and cheaper than that using commercial kit or other methods. Consequently, the mGITC/SC is an economical DNA extraction method that could be a useful tool for detecting MAP from fecal specimens.

Hasoon, Mayada F. | Mohammed, Majed H. | Jubrael, Jaladet M. S.
A primary fibroblast cells from embryos of brown quail Coturnixypsilophora has been established and partially characterized. The cells were maintained in Modified Eagle’s medium (MEM) supplemented with 10% fetal bovine serum. The cells were able to grow at temperatures between 35°C and 38°C with optimum temperature of 37°C. The growth rate of primary quail fibroblast cells increased as the FBS proportion increased from 5% to 20% at 37°C with optimum growth at the concentrations of 10% or 15% FBS. The cells showed no microbial contamination throughout the period of experiment and the total chromosome number of a diploid cell was 78, according to karyotyping and chromosome analysis. The susceptibility of quail primary cells for avian viruses was investigated in this study after inoculation with ND and IB viruses. Both viruses showed a satisfactory CPE development and the infectivity were assayed by virus titration (TCID50). This suggests that the quail primary cells can be used for isolation of various avian viruses with further steps of infectivity confirmation in the future.

A study was conducted on 240 scavenging chickens randomly obtained from various districts from the state of Penang, Peninsular Malaysia. The chickens were closely examined for visible ectoparasites in the laboratory. The ectoparasites were collected using a blunt forceps and stored in universal bottles containing 70% ethanol. Ten species of ectoparasites were noted which consisted of five species of lice, two species of mites, two species of ticks and one species of chigger. The lice identifi ed were Menopon gallinae, Menacanthus pallidulus, Lipeurus caponis, Goniocotes gallinae and Goniodes dissimilis. These lice occurred in the fl uff of the feathers of the body especially the neck, back, abdomen and wings. The mites were Megninia sp. and Pterolichus sp. Examinations of the ears and combs revealed Haemaphysalis sp., the hard tick. Meanwhile, Ornithonyssus sp., the soft tick was found on feathers, whereas chigger, Leptotrombidium sp. was found attached to the skins. The study also revealed that M. gallinae was the most common ectoparasite with 76.7% occurrence, followed by Pterolichus sp. (69.6%), L. caponis (63.3%), M. pallidulus (41.7%), Leptotrombidium sp. (17.5%), G. gallinae (9.5%), Haemaphysalis sp. (6.7%), Megninia sp. (3.8%) and Ornithonyssus sp. (3.8%). The least common ectoparasite was G. dissimilis occurring in 2.1% of the chickens.

The development and availability of follicles is an indicator to predict which of the follicle sizes are suitable to recover the oocytes assisted by means of ultrasonography of transvaginal oocyte retrieval (OPU). Thus, the study was done in order to characterize the follicular recruitment and distribution in response to the repeated removal of follicles, and thus to determine the availability of follicles and immature oocytes harvested repeatedlyfor two consecutive days of OPU in beef cows. Results indicated that 24-h OPU showed significantly greater numbers of medium and large follicles than small categories (P<0.05). However the 48-hr of OPU does not showed any differences of follicles categories (P>0.05). The mean total number of follicles and immature oocytes recovered were higher (P<0.05) in 24-hr OPU (13.76±1.2 and 7.38 ± 1.7) compared to 48-hr OPU (9.08 ± 1.5 and 3.54 ± 1.00) with the oocyte retrieval rate of 51.22% and 38.17%, respectively. The morphological classification indicated the 24-hr oocyte retrieval produced 62% of suitable immature oocytes that can be used for in vitro embryo production. In conclusion, the repeated removal of two consecutive days of OPU has averted the development of dominant follicle, and thus, gave an atmosphere to the subordinate follicles to continue growth relatively to an equal proportion of small, medium and large categories of follicles. Due to the reduction of follicle and recovery rate at 48-hr it is suggested that OPU be carried out later than 48 hour so that the follicle has more time to increase the diameter size.

The aim of this study was to investigate the bacteria found in different parts of the genital system in cows and the susceptibility to different types of antibiotics. The genital systems of sixteen cows were collected from Al-Hilla, Iraq slaughterhouse. Isolation and identification of bacteria were made for each part of the genital system and antibiotic susceptibility tests was conducted to the isolated bacteria. The results of this study indicated that there were several types of bacteria present in the genital systems of cows. Different species of bacteria were isolated from the samples including, Escherichia coli (28.97)%, Klebsiella spp. (16.82)%, Salmonella spp. (14.95)%, Proteus spp. (13.08)%, Staphylococcus aureus (11.21)%, Staphylococcus epidermidis (8.41)% and Streptococcus spp. (6.54)%. In vitro susceptibility towards different types of antibiotic indicated high susceptibility of Escherichia coli to antibiotic group impenem and ciprofloxacin, while Klebsiella spp. was found to be most susceptible to ciprofloxacin and amikacin. Both Escherichia coli and Klebsiella spp. showed resistance to piperacillin and tetracycline. It was concluded that Escherichia coli was the most predominant bacteria in genital system of cows and were most susceptible to antibiotic impenem and ciprofloxacin.

Many parasitology laboratories practiced the McMaster technique as a method in obtaining the quantitative diagnosis of Strongyle eggs burden in farm animals especially ruminants. The McMaster technique also play a crucial role in faecal egg count reduction test (FECRT) for anthelmintic resistance identification. Some laboratoriesrecommend two-chamber counting method while some recommend single chamber counting method. This study focuses on the comparison between single and double counting in McMaster technique fordetection of Strongyle egg count. In this study, it is shown that there is no significant difference between both methods basedon the p-value obtained which is p>0.05 from 127 fresh goat faecal samples. The techniques practised during the study follow the standard established technique. Single chamber counting is suitable for a large number of faecal samples from big herds because it is faster, less laborious and produces sensitive and reliable results in Strongyle egg count. As more commercial farms are set up, there is a need to conduct a fast and efficient test to help farmers evaluate their livestock worm burden.

The Department of Veterinary Services (DVS) established a subsidy programme to build low cost swiftlet houses, under the auspices ofthe eKasih programme. This programme is aimed at aiding entrepreneurs in the swiftlet industry to produce good qualitybird’s nests. In 2013, eleven swiftlet houses under eKasih Program in Johor, Perlis and Pahang were chosen randomly to be evaluated after a year of completion. The main factors affecting its functionality, such as temperature, relative humidity and light intensity inside the swiftlet houses were recorded and analysed. The results showed that most of the eKasih swiftlet houses built under this programme did not meet the recommended in house conditions due to several reasons. The houses built in this programme failed to attract the birds into the houses to build nests. Although there were some houses that produced bird’s nests, it was found to be substandard in terms of quality. Thus, this study revealed the importance of various factors needed for the successful establishment of swiftlet houses to produce good quality bird’s nests.

A study was conducted on 16 commercial free range chickens (8 malesand 8 females) sourced from Alor Setar, Kedah in order to determine the prevalence of ecto and endoparasites. Results showed that there were 12 different species of ectoand endoparasites from these chickens. Four (4) species of ectoparasites which consist of three lice and a tick have been discovered. The highest prevalence of ectoparasite was Menopon gallinae (93.8%). The other ectoparasites were Menacanthus pallidulus (81.3%), Haemaphysalis sp. (37.5%) and Lipeurus caponis (18.8%). On the other hand, eight species of endoparasites which consist of four nematodes and four cestodes were discovered. Rallietina echinobothrida showed the highest prevalence of endoparasite (100%) followed by Heterakis gallinarum (93.8%), Acuaria spiralis (87.5%), Ascaria galli (81.3%), Rallietina tetragona(43.8%), Gongylonema ingluvicola (37.5%), Hymenolepis carioca (12.5%)and Hymenolepis cantiana (12.5%). Endoparasites infestation was recorded highest on male chicken (52.6%) compared to female (47.4%). However, there was no statistically significant difference betweenthe number of endoparasites and both sexes; t (14) = 0.817, p>0.05.
